Empathy is just understanding someone else's emotional perspective. I don't it means you have to necessarily share their pain, as much as understand it. A sociopath by it's definition is someone with antisocial tendencies. Maybe some people are chemically unable to feel empathy, but I tend to think of most things as learned behavior, even if it's not direct, but more adaptive. That's all from my own experience, though, and that's obviously highly subjective. To say people who troll are sadists, though, is just incredibly narrow minded, even if it was a survey.

When I said I can choose to feel empathy, I mean that I can choose to lend myself to their plight. I can generally understand where a person is coming from.
